<Presentation title>



OpenGL has changed since

OpenGL 1.1

• Graphics hardware for OpenGL 1.1

• Vertex Transformation (dynamic rotation)

• Pixilation – determine which pixels are drawn for a

primitive

• Hardware has changed

• Graphics hardware is massively parallel

NVIDIA K5000 has 1536 cores

• Graphics hardware has much more memory

NVIDIA 6000 has 6GB

• OpenGL has followed

• Allocate buffer objects (memory on graphics hardware)

• Use programmable shaders to tailor graphics capabilities



FEMAP Graphics Architecture v11.0

• FEMAP v11 includes support for Vertex Buffer Objects (VBOs)

• Require at least OpenGL 2.1

• Only need OpenGL 1.1 if VBOs not used

• VBOs enable vertex data to be stored on the graphics card

• Vertex data is location, normal and texture

• Drastically reduces data transfer per frame

• Limited by graphics memory

• More graphics memory means more performance

• Up to an order of magnitude performance improvement

• Dynamic rotation of large models



FEMAP Graphics Architecture Progress

Model Description Performance Improvement

1600 solids – each solid is a 100x1x1 brick

with the four long edges filleted to .1 radius

Model 1 in 10.3.1/64 with no vertex arrays

440ms, in dev 64 release 50ms (8.8 times

faster)

1600 solids – each solid is a sphere of

radius 1


1213ms, in dev 64 release 270ms (4.5 times

faster)

640,000 quad4 elements Model 3 in 10.3.1/64 with no vertex arrays

427ms, in dev 64 release 408ms but with VBO

on, 64ms (6.3 times faster) and uses about

151MB of graphics memory

1,919,488 tetra10s – 16 solids of

100x100x1 block – each block has

119,968 elements


746ms, in dev 64 release 750ms but with VBO

on, 130ms (5.7 times faster) and uses about

252MB of graphics memory

*AMD v3900 card



FEMAP Graphics Architecture Progress

Limits of Performance on Dell Precision

Mobile Workstation

• I7-2860QM – 2.5 GHz

• 16 GB RAM

• nVidia M2000 – 2GB RAM Graphics

Multiple Copies of the Boeing ISS

Laboratory Module

4.5M Nodes and Elements

Dynamic Rotation Performance ~8x faster,

v10.3 to v11 w/VBOs



FEMAP Graphics Architecture Future (v11.1)

• Single copy of graphics entity data within a model

• Used to have a copy per view of model

• Significant <Ctrl-G> improvement as raw data already in

memory

• Dynamic rotation better than original not quite as good as VBO

• But can handle much larger models

• Phased introduction

• First release accelerates solids and plates

• Deformation, Animation

• Contour, Criteria



FEMAP Graphics Architecture Future (v11.1)

• Uses Geometry Shader functionality that requires OpenGL 4.1

• Moves facet generation from CPU to GPU

• Dramatic reduction in volume of data required

• Shader uses same data for filled faces or edges

• State changes done in GPU on the fly

• Such as shrink, plate thickness

• Deformation – faster animation generation

• Contour only faces with results – good for contact

• Contouring done in fragment shader

• Better quality near min and max contour values

• Better quality interior interpolation



FEMAP Graphics Architecture Future

V11.1 – OpenGL 4.0/4.1 Graphics

Takes advantage of Parallel GPU Processors, some graphics

cards now have 448 processors, in FEMAP v10.1/11.0,

FEMAP controlled processor utilization, now the graphics

driver optimizes parallel processor usage.

Not only are OpenGL 4.x graphics faster, they use

significantly less graphics memory –

Consider a block meshed with 34584 elements and 50975

nodes.

OpenGL 1.0 data requirement is 46x34584 = 1,590,864 floats

OpenGL 2.0 data requirement is 292x34584 = 10,098,528

floats

OpenGL 4.0 data requirement is (3x50975)+(10x34584)

= 498,765 floats

Geometric Modeling – Non-Manifold Add

Non-Manifold Boolean Add

• FEMAP v10.3.1 and

Previous – Parasolid had

no tolerant modeling

functionality for non-

manifold body, everything

worked at 1.0E-6 Precision

• V11.0.x add some Edge

Precision modifications, but

not full tolerant modeling





• In close cooperation with

the Parasolid Team,

identified use cases, test

data, and functionality for

tolerant Non-Manifold

Boolean Add

• Now works similar to

Parasolid “Stitching” or

“Sewing”, bringing edges

and vertices together





• Overlapping

• Offset

• Gap



Geometric Modeling

Sweep Surfaces Into Solids – Geometry, Solid, Sweep



Geometric Modeling – Surface From Mesh

• Special Case Coding for Ruled Surfaces

• More robust



Geometric Modeling – Solid Between Surfaces

Creates a new Solid, swept

between two user selected faces,

twist controlled by the user

selecting a anchor point on each

surface -




Blend Factor, similar to FEMAP’s Blend Spline has a factor to control its shape

– 0.5,1.0, 1.5

Non-Manifold Boolean Add Details

• Algorithm Starts with First body, and adds the

next closest body one at a time

• Tolerance – Similar to Stitch/Sew

• Incremental Checking – After each step,

checks to see if the resulting Parasolid body

is ok, if not, rolls back and skips that solid.

Depends on the quality of the geometry,

on this ship model, not required. On

others, it is. It’s slower with the check,

use it the first time, you’ll know if you

need it in subsequent models.





Example

• 1119 Surfaces

• Recommend that the selection

be broke up into sections for

larger models

• FEMAP highlights Free Edges

so you know what got

connected




• Guaranteed mesh continuity

• Can now using Meshing

Toolbox to create the best

mesh possible



FEMAP v11 – Attached Results

Attached Results

• No effective limit for number of attached results files

(99,999,999)

• 100% coexistence for Internal or Attached results, i.e. Output

Processing across any type, or any number

• Attached results can be internalized, including a subset

• File Size/Date update detection

FEMAP v11.1 – Attach Results

Expanded to include .XDB files

• Support attaching to NX and

MSC XDB

• Code all native to FEMAP

• No external API/libraries

necessary

• No FORTRAN

• Greatly benefits former

PATRAN customers with

existing XDB results data and

those transitioning from

PATRAN to FEMAP




MSC Nastran -

Support HK (original) and Binary Tree ( MSC 2005 and later ) storage methods.

Method selected with DBCFACT on NASTRAN command

• 0 - no multi-key format (default) - This produces the original format XDB file

used by MSC and NX

• 2 - auto-select multi-key format - Data blocks possible in both formats

• 4 - multi-key format - Data Blocks are always written using the new Binary

Tree method.

All three options are supported.




Limitations –

• Superelements are not supported

• 1 NASTRAN Database per XDB supported

• Design Optimization not yet supported

FEMAP v11.1 Meshing Enhancement - Tetrahedral

Two Element through Thickness

Option



FEMAP v11.1 Meshing Enhancement - Tetrahedral

Latest Tetra Mesher eliminates

most flat tetrahedrons



FEMAP v11.1 – Meshing Toolbox Updates

Control Pad Alignment in

Meshing Toolbox

• Default

• Tangent

• Along Vector

Added new option to Pad &

Washer at the same time



FEMAP v11.1 – Element Support – NASTRAN

Pyramid

• NASTRAN Read/Write

Support

• Manual Creation

• API Access

• Investigating integrating into

FEMAP’s Solid Meshing

Routines



FEMAP v11.1 - Grouping

Group – Operations – Generate

“NonManifold Edges” will force

breaks at “T-Junctions”

In this sample panel, 105 groups

are automatically created

representing each interior panel

and rib



FEMAP v11.1 – Mesh Copy - Offset

Copy Elements along their normals, with or without the corner

correction used in offsetting shells into solids…



FEMAP v11.1 – Modify, Project

• Added new commands –

• Modify->Project->Points and Modify->Project->Nodes

• Removed old commands on the Modify->Project menu that

already projected points and nodes to specific entity types

• Improved the projection algorithms to accept multiple

curves/surfaces to project onto, and to allow projection along a

vector in addition to "closest" for all types.

• Added the feProjectOnto() API method to access the new

capability and converted old API "project" calls to use the new

internal functions.



FEMAP v11.1 Performance Improvements

• Visibility Dialog Box – underlying code was

rewritten to more quickly populate the

Property, Material, Group selection boxes

• Enhanced load expansion from geometry

to a mesh for elemental face-based loads

on surfaces (Pressure, Heat Flux,

Convection and Radiation). Previously on

large models these could take a long time.

For example a model with 1,000,000

elements meshed on a solid that had 300+

surfaces with pressure loads on ~120

surfaces took around 5 minutes to expand

to the mesh faces. Using the new method it

takes between 2 and 3 seconds.



FEMAP v11.1 – User Interface

Optionally display group and layer

information when using “Tooltips”

Appears both in the Tooltip and

FEMAP’s Entity Info Window



FEMAP v11.1 - Charting Enhancements

• Added new data series type: Value vs.

Value. Allows for plotting of quantities

such as applied force vs. displacement

at a specified location

• Reorganization of chart data series

dialog to only show relevant items

• Improved rendering when copying

charts to the clipboard at non-screen

resolutions

• Increased user control over

fonts/labels/colors for chart entities



Other Updates

• Freebody: added ability to force freebody calculations to only consider

applied, constraint and multipoint constraint forces from GPFORCE data

block. By default, Femap will use applied, spc and mpc forces from OLOAD,

SPCFORCE and MPCFORCE requests if that data was not available in the

GPFORCE block, however there were some cases where Nastran would not

report the same number in both places (thermal applied loads across rigid

bodies being an example)

• Freebody: added validation tool to check if all requested values exist in the

result set

• Freebody: updated freebody listing tools to provide more relevant output

• NASTRAN: enhanced restart support

• NASTRAN: added support for Normal Modes Analysis with Design

Optimization



NX Nastran v9

Shouldn’t be a problem for v11.1

Dynamics:

Laminate ply results in transient dynamics

Relative motion datablock for enforced motion dynamic analysis

Residual vector changes

Advanced nonlinear:

Plastic-cyclic material model(MATPLCY)

Bolt preload with 3D solid elements

Edge-to-edge glue(Axisymmetric, Plane Stress/Strain )

Probably > 11.1

Dynamics:

AF mode normalization à Joe is this useful???

Rotordynamics:

Dependent bearing properties

CBEAR and PBEAR
